Hi there. I bought an Xperia M5 Dual Model E5663 online and I'm worried that It won't be supported by my UK network (BT Mobile) and no updates might come. Based on 4g.co.uk BT mobile supports 800, 1800 & 2100. EE (which BT bought almost 2 years ago but claims they are still a separate entity as BT Mobile is still an MVNO) supports 1800 & 2600. The reseller told me he had british customers who bought this model and never had a problem. BT mobile cannot guarantee that the phone when set to Auto that it will pick up EE's signal. Any advice please? Many thanks.
